Application July a, 1936. 861111 No. 89,157

a mm. (01. 111-535) This application relates to tacking strips forautomobile upholstery and discloses an improved strip or greaterdensity, pliability, hardness, and smoother finish than strips now inuse.

An embodiment of the invention is shown in the accompanying drawing, inwhich Fig. 1 is a perspective view 01' a section of tacking strip;

Fig. 2 is a perspective view of the strip of Fig. ,1 with the variouslayers cut away and the paper unwound to show the construction.

Referring to the drawing it will be seen that the tacking strip consistsof a core in about which is wound a wrapper of paper H which is in turnencased by a thick coating 01' asphalt I2 which is covered by a skin orcover of paper it.

The core ill may be asphalted paper or untreated paper crushed intoproper shape and laid straight.

The wrapper H may also be either plain or treated paper, formed intostrips and wound spirally about the core. In the particular embodimentof the drawing the strips of the wrapper I! have been crushed from flatthin 12 inch wide strips into narrow crushed strips of approximatelyone-half inch in width and one-eighth inch in thickness.

Encasing the wound wrapper ii is a coating ii of asphalt approximatelyone-sixteenth inch thick This is wrapped in a spirally wound paper coveror skin it which may be a single smooth thin wide strip one and one-halfinches wide, continuously wound around the interior of the strip, orwhich may comprise several such strips overlapping each other, with eachbeing continuously wound.

A principal characteristic of the present strip is the presence of thelayer of asphalt l2. Its presence helps form the strip components into aunitary and dense mass, and enables the strip to be made more dense thanis an all-paper strip,

and permits the use of the skin tight cover or skin H, thus providing asmooth thin skin for the strip, and permits the strip to be bent andtwisted withoutunravelling.

Now having described my invention, reference 5 will be had to the claimswhich follow for a determination of the scope of the monopoly sought.

I claim:

1. In a tacking strip, a core, an encasing thick coating of asphaltoutside said core, and an outer skin of thin flat smooth paper ribbon.

2. In a tacking strip, a core, a spirally wound twisted paper wrapperthereon, an encasing thick coating of asphalt outside said wrapper, andan outer skin of thin fiat smooth paper ribbon.

3. In a tacking strip, a core, a spirally wound twisted paper wrapperthereon, and an outer skin of thin fiat smooth paper ribbon woundspirally on the wrapper, there being an encasing thick coating ofasphalt outside the wrapper.

4. In a tacking strip, a core, a spirally wound twisted paper wrapperthereon, and an outer skin of thin flat smooth paper ribbon woundspirally on the wrapper, there being an encasing thick coating ofasphalt outside the wrapper and inside the skin.

5. In a tacking strip, a core, a spirally wound twisted paper wrapperthereon and an outer skin oi thin fiat smooth paper ribbon woundspirally on the wrapper with the two windings being oppositely wound,there being an encasing thick coating of asphalt outside the wrapper.
